This is thread is about a Cessna 152 so talking big radials is irrelivent in this case.
Got it. Perhaps you're slow enough you can't follow along, so we'll break it down for you, so that you can.
The only reason for needing to touch the throttle on start is to control exessive RPM, I except that some fuel may get into the one cylinder but most of it will end up in the airbox if the engine is primed before the walk around is done.
Once again, where the fuel goes depends on the position of the crankshaft, camshaft, lifters, pushrods, and valves in the Cessna 152; it may drain into the induction, it may drain into a cylinder, it may stay in the cylinder head, for that matter.
With the 0-235, a cold start is a wet start, whereas starting lean or dry in hot weather is the general norm. It also applies to radial engines.
On the subject of prime, for those who aren't aware, failure to lock your primer can lead to a fire, or an engine failure.
